Do GLP-1 peptides damage teeth?

THE CASCADE

The American Dental Association's October 2025 guidance for patients on these peptides spells out the cascade: GI side effects (nausea, vomiting, reflux) lower the pH inside the mouth, and lower oral pH eats at tooth enamel.

Saliva normally buffers the acid; when saliva drops, the defense drops with it. So the path is peptide → GI side effects → low oral pH → enamel erosion.

THE FRAMING

The "Ozempic teeth" framing names a real cluster of dental problems, but with the wrong cause. The dentist-facing literature treats the issue as preventable through routine dental care and attention to reflux.

There isn't a peptide-specific dental mechanism in the evidence. The chain is the GI side effects.

What this means

The popular framing names a real cluster of problems with the wrong cause.

The peptide isn't doing the damage. The cascade is.

Do GLP-1 peptides damage the kidneys?

Not directly. The kidney risk in the literature runs through severe dehydration from GI symptoms.

Does Ozempic cause "Ozempic face"?

The face does look different. The reason is fat loss, not the peptide.

Do GLP-1 peptides affect birth control?

For tirzepatide (Mounjaro and Zepbound), the label is explicit. For semaglutide (Ozempic and Wegovy), it isn't.
